How is it possible that energy can neither be created nor disappear, but simply transformed from one form to another, generating new energy without consuming other energy.
-
This is in the second year of junior high school, because there is energy consumption in the perpetual motion machine, because (** energy) is less than (the energy required for movement), so the energy is gradually decreasing, and will eventually stop. I'm too slow to type much, sorry.
-
It's not impossible. It's impossible on Earth.
Because there are external factors in any exercise consumption.

1. The law of conservation of energy: energy will neither be generated out of thin air nor disappear out of thin air, it will only be transferred from one object to another, or from one form to another, and in the process of transformation or transfer, the total amount of energy remains the same.
2. The second law of thermodynamics: it is impossible to absorb heat from a single heat source and completely convert this heat into work without other effects.
3. In terms of working principle, the idea of a perpetual motion machine violates the basic laws of thermodynamics, so it is impossible to realize it. The four basic laws of thermodynamics are the most solid laws in natural science, and they are the crystallization of science and technology and experience for hundreds of years.

The perpetual motion machine cannot be realized because it violates the law of conservation of energy in thermodynamics. The principle of perpetual motion machine is that it does not need to input energy and energy from the outside world, and can continue to do work under the condition of only one heat source, that is, it can operate forever without consuming energy, which does not conform to the principle of energy conservation.
Why can't a perpetual motion machine be realized
According to the law of conservation of energy, energy is neither created nor disappeared out of thin air, but only transferred from one object to another, or from one form to another, and the total amount remains the same.
The laws of thermodynamics are the laws that describe the laws of heat in physics, including the zeroth, first, second, and third laws, in which the idea of a perpetual motion machine violates the first and second laws.
The four basic laws of thermodynamics are considered to be the most rigorous disciplines in the natural sciences, and are the crystallization of hundreds of years of science and technology and experience.

Perpetual motion machines violate the laws of conservation of energy and thermodynamics
Perpetual motion machine is a kind of so-called machinery that can continuously move and do work externally without the need for external input energy, energy or only one heat source;
The law of conservation of energyThat is, the first law of branch loss heat preparation refers to the total energy in a closed system remains unchanged, in which the total energy is generally no longer just the sum of kinetic energy and potential energy, but the total amount of static energy, kinetic energy, and potential energy;
The laws of thermodynamicsIt is a law that describes the laws of heat in physics, including the zero law of thermodynamics, the first law of thermodynamics, the second law of thermodynamics, and the third law of thermodynamics.
Therefore, a perpetual motion machine is not possible.
In ancient times, it was absolutely impossible for people to fly in the sky ... It is not possible for people to walk on the moon in modern times ... But it is absolutely impossible for this to be possible today ... >>>More

Inertia. Thinking about problems requires energy, so people always think that they can think less about problems and think less about problems, and wish they didn't think about it for the rest of their lives, but life forces us to do this and that, so people are used to doing things without brains. >>>More
This is understandable, you always want him to know your suffering, but also know your helplessness, fortunately, one day, under the osmanthus tree, beside the road, on the corner, you show him so many years of suffering, you hug your head and cry, but in most reality, you don't have this opportunity, you just watch him She got married, gave birth to children, and posted ** in the circle of friends, that's all.
It would be too hasty for the two of you to live together without knowing anything. >>>More
